Hello, I'm going to be building a subwoofer for the sound system in my room. I was originally going to use the Dayton 12" DV-310 sub because of its lower price, but I began to consider the MkIII since the price difference between the 2 wasn't too great. Sooooooo, are there any major acoustical differences between the two? The receiver I'm going to use it with is hooked up to my computer. The sub will be fed everything - music, computer games, and movies. I will be using the 250watt plate subwoofer amplifier on PE (or 272 @ 4ohms according them) and building my own box (that should be fun...) My 8" AR sub has been great, but I need more boom!
